It's nice; I'll admit it is small though. Perhaps you could make it a 3 stage Koth map like Dustbowl (but instead of 2cp make it Koth *best 2 of 3 rounds*)
One problem: Lighting. I don't know if it's just me, but the white dev texture you're using for the ground is really bright. and the map occasionally looks like it's completely black. If you need I can provide screenshots.
But other than that it looks great. I look forward to seeing where this goes.
